SPECIFICATION forming part of Letters Patent No. 609,891, dated August30, 1898.

Application filed January 22, 1897. Serial No. 620,170. (No model.)

To @ZZ whom it may concern:

Be it known that I, J AMEs MAOPHAIL, a citizen of the United States,residing at Blue Island, in the county of Cook and State of Illinois,have invented a certain new and useful Improvement inReaping-Machines,which is fully set forth in the followingAspecification, reference being had to the accompanying drawings, inwhich- Figure l is a plan view of a reaping-machine constructedaccording to myinvention. Fig. 2 is a side elevation thereof in thedirection of the arrow of Fig. 1 with the drivingwheel omitted, showingthe platform tilted up. Fig. 3 is a similar elevation showing theplatform tilted down. Fig. 4 is a rear elevation of the machine. Figs. 5and 6 are detail views of the attachment of the tilting-lever to thetilting-rod. Fig. 7 is a detail elevation of the seat-casting. Fig. Sisa plan View of the same.

My invention relates to reaping-machines, and particularly to mechanismtherein adapted to tilt the platform and raise or lower the sickle-barand to the seat-mounting and connections.

In the drawings I have omitted certain parts of the complete machinewhich have no connection withmy-improvement, and many of the parts shownare of ordinary construction and will be but brieiiy described.

Referring to the drawings by letter, A represents the platform, A thesickle-bar, B the.

grain-wheel, and C the gear-frame, of areapin g-machine. Thedriving-wheel D is mounted upon an axle D', forming part of thewheel-frame E. To the said wheel-frame is secured a yoke E', in which ismounted the roller E2. The gear-frame C is swung from the roller E2 bythe U-bolts e passing over the same. The roller AE2 is disposed nearlyin line with the axle of the grain-wheel B, and the forward edge of theplatform is thus free to tilt up and down from the axis so formed.

Upon the axle D', outside of the drivingwheel, I mount a casting F,comprising a sleeve F', adapted to surround and be secured to the saidaxle by the pin f, a forwardly-prolading Mm F2, and a Shortrearwardly-extending bracket F3. In the end of the arm .the foot-leverf4.

F2 is formed a slotf, adapted to receive a stud or pivot f2, upon whichis pivotally mounted The said lever has appropriate connections with therake disposed in the usual manner and only part of which are shown inFig. l. The seat F5 is mounted upon the post F6, to the lower end ofwhich is securedthe footboard F7. The post F6 is rigidly secured to ashort horizontal bar F2, the inner end of which fits within a box f3,formed in the bracket F3 of the casting F. The bar FS is secured in thesaid box by the pin f4, which in turn is held by the cotterpin f5.

Hitherto in this class of machines the seat and its connections havebeen so secured to the axle and the foot-lever so mounted upon thefootboard, such as F7, that it has been impracticable to remove the seatwhen desired to drive the machine through a narrow gate. This has proveda great practical inconvenience, but is entirely obviated by the aboveconstruction, with which the seat may be readily removed by withdrawingthe cotter-pin f5 and pin f4 and as quickly replaced again. Thefoot-lever being mounted upon the casting F in no wise interferes withthis removal.

To the gear-frame C the rear end of a tongue or pole G is pivoted, as atg. A diagonal brace-rod G is also preferably employed pivoted at g to4the pole and at g2 to the platform.

Referring more specifically to the tilting mechanism, I-I is a castingcomprising a short arm H', pivotally mounted, as at h, upon the axle D,a socket H2, and a rack-segment H3. The suspending-bar H4L is pivoted,as at 7L', to a bracket H5, mounted upon and forming a part of thegear-frame C. The other end of the suspending-rod is adjustably secured,through one of the perforations h2, to the lower end of the rack-segmentH2. The rear end of the carrying-bar I is rigidly'mounted in the socketH2, above described. Its forward end is bent, as at I', and is adaptedto slide in a guide-box I2, mounted upon one side of the pole G.

A tilting lever .I is pivotally mounted upon the carrying-bar I, as atj. At its rearward end it is provided with a handle J', the dog IOO .slides forward in the guide-box I2.

j, and hand-latch jz, whereby the lever can be moved along and securedupon the racksegment H3. The forward end of the leverJ in front of itspoint of pivotal connection with the carrying-bar is provided with ashort upwardly-extending arm J 2, to the upper end of which is securedone end of a coiled contraction-spring J 3. The other end of the saidspring is secured by an eyebolt and nut to a bracket J4, mounted uponthe carrying-bar. Any other means equivalent to the bolt and nut js,permitting the adjustment of the tension of the spring, maybe employed.

To the tilting lever J, between its pivotal mounting upon thecarrying-bar and the handle J is rigidly secured a small bracket K, inthe lower part of which there is formed the bearing for a swivel-pin K.The said pin-is provided with a head K2, in which is formed ascrew-threaded aperture adapted to receive a screw-threaded rod K3. Theupper end of the rod K3 is provided with a crankhandle K4. The lower endis rotatably mounted upon the platform, as at K5.

The ope-ration of these parts will be readily understood in connectionwith the drawings. In Fig. 2 the machine is shown in its normalposition, with the sickle-bar raised. When it is desired to lower thesickle-bar, the tilting lever J is moved down the rack-segment H3. Therod Kis thus depressed in respect of the carrying-bar I,the forward endof which The front edge of the platform and the sickle-bar are thuslowered to any desired extent Within the range of adjustment of therack-segment.

y When it is desired to raise the sickle-bar, the

tilting lever J is moved upward along the l rack-segment and the frontend of the platform. is raised by the rod K3. During this operation thespring J 3 materially assists the operator, aiding him in overcomingwhat otherwise is a very considerable weight, and the said sprlng may beso adjusted in tension rals to permit of the tilting o f the machinewith but a minimum of exertion. By means of the adjustablesuspension-bar H4 and the screw-threaded rod K3 it will be seen that therange of tilting of the platform can be adjusted either higher or lower.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, isj A l. In areaping-machine, the gear-frame Cpivotally mounted in relation to the drivingwheel, the pole Gr pivotallyattached to the gear frame, the carrying bar I pivotally mounted inrelation to the driving-wheel and having its forward end slidinglymounted on the pole G and the rear end formed in a segmental rack andadjustably connected to the gear-frame C, the substantially L-shapedlever J pivotally mounted on'the bar I and having the spring-latchcooperating with the segmental rack, the screw-threaded rod K3 havingbearings in the frame O and in the pivotal nut K2 carried by the bar I,and the spring J3 connected to the bar I and to the upturned end of thelever J, substantially as and for the purposes described.

2. In a reaping-machine, the axle D'; the casting F mounted upon theaxle; the footlever F4 mounted upon thecasting; and the seat F5 and itsconnections detachably mounted in the said casting. v

3. In a reaping-machine, the axle D', the casting F, comprising theforwardly-extending arm F2 and the bracket F3, provided with a box f3;the foot-lever F4 mounted in the said arm F2; the seat F5; the seat-postF6; and the horizontal bar F8 secured at one end to the seat-post anddetachably secured at its opposite end in the box f3, substantially asdescribed.
